RadioMaster T8L ExpressLRS 2.4GHz Radio ControllerRadioMaster T8L: The Compact ExpressLRS Radio Controller Lets be honest: your current transmitter is basically a chunky VCR from 1994 that takes up half your flight bag. The RadioMaster T8L is the ExpressLRS radio controller for pilots who actually want to fit a sandwich in their backpack. It is the first screenless ELRS 2. 4GHz unit officially blessed by the devs, meaning no more squinting at a 1 inch LCD like youre trying to play Snake on a Nokia.
